将前景色和工具提示绑定到 DataGrid

Question

我有一个 DataGrid - 有

1. 一个隐藏列 (SubjectFull) 和一个包含最多 60 个主题的可见列，称为“Subject”。

2. 名为“未读”的栏 - 这是尚未未读的情况下的图像。

我可以获得一个工具提示来仅显示网格可见部分的SubjectFull 值，但是当我向下滚动时它就会变得混乱。

For Each row As DataRowView In DGV.Items.OfType(Of DataRowView)
Dim DGRow As DevComponents.WPF.Controls.AdvGridRow = DGV.ItemContainerManager.ContainerFromItem(row, True)
Dim vTooltip As String = row("SubjectFull")
DGRow.ToolTip = vTooltip
Next

我正在尝试使用

来解决这个问题

 Dim DGV As New DGVx
 With DGV
 .Name = "Inbox_DGV"
 .ContextMenu = ReturnContexMenu()
 End With
 RegisterControl(Inbox_Grid, DGV)
 Grid.SetRow(DGV, 1)
 Inbox_Grid.Children.Add(DGV)

 Dim vStyle As New Style(GetType(DevComponents.WPF.Controls.AdvGridRow))
 Dim vSetter As New Setter
 With vSetter
 .Property = DevComponents.WPF.Controls.AdvGridRow.IsSelectedProperty
 .Value = New Binding("Select") With {.Mode = BindingMode.TwoWay}
 End With
Dim vSetter2 As New Setter
With vSetter2
 .Property = DevComponents.WPF.Controls.AdvGridRow.ForegroundProperty
 .Value = New Binding("Unread") With {.Mode = BindingMode.TwoWay}

End With
vStyle.Setters.Add(vSetter)
vStyle.Setters.Add(vSetter2)
DGV.Resources.Add(GetType(DevComponents.WPF.Controls.AdvGridRow), vStyle)

复选框（选择）的绑定效果很好，但我正在努力寻找一种方法将字符串从隐藏列绑定到行，并为存在未读图像的行分配颜色。

任何指点，将不胜感激

更新 - 我现在可以使用工具提示，并且有另一个隐藏的整数字段来表示“读取” - 如果值为 0，则该行需要为红色，否则为默认值（或黑色）

 Dim vStyle As New 
Style(GetType(DevComponents.WPF.Controls.AdvGridRow))
Dim vSetter As New Setter
With vSetter
 .Property = DevComponents.WPF.Controls.AdvGridRow.IsSelectedProperty
 .Value = New Binding("Select") With {.Mode = BindingMode.TwoWay}
 End With

 Dim vSetter2 As New Setter
 With vSetter2
 .Property = DevComponents.WPF.Controls.AdvGridRow.ToolTipProperty
 .Value = New Binding("SubjectFull") With {.BindsDirectlyToSource = True}
 End With

 Dim vSetter3 As New Setter
 With vSetter3
 .Property = DevComponents.WPF.Controls.AdvGridRow.ForegroundProperty
 .Value = Brushes.Red '<--------This needs to be the value if FlagRead = 1
 End With
 With vStyle.Setters
 .Add(vSetter)
 .Add(vSetter2)
 .Add(vSetter3)
 End With
 DGV.Resources.Add(GetType(DevComponents.WPF.Controls.AdvGridRow), vStyle)

Answer 1

弄清楚了:-)

 Dim vStyle As New Style(GetType(DevComponents.WPF.Controls.AdvGridRow))
 Dim vSetter As New Setter
 With vSetter
 .Property = DevComponents.WPF.Controls.AdvGridRow.IsSelectedProperty
 .Value = New Binding("Select") With {.Mode = BindingMode.TwoWay}
 End With

 Dim vSetter2 As New Setter
 With vSetter2
 .Property = DevComponents.WPF.Controls.AdvGridRow.ToolTipProperty
 .Value = New Binding("SubjectFull") With {.BindsDirectlyToSource = True}
 End With

 Dim vSetter3 As New Setter
 With vSetter3
 .Property = DevComponents.WPF.Controls.AdvGridRow.ForegroundProperty
 .Value = Brushes.Red
 End With

 Dim vTrigger As New DataTrigger
 With vTrigger
 .Binding = New Binding("FlagReadFull")
 .Value = 0
 .Setters.Add(vSetter3)
 End With

 With vStyle.Setters
 .Add(vSetter)
 .Add(vSetter2)
 End With
 vStyle.Triggers.Add(vTrigger)
 DGV.Resources.Add(GetType(DevComponents.WPF.Controls.AdvGridRow), vStyle)
